Re: 1.7.10 cygrunsrv.exe fails with "fork: 11, Resource temporarily unavailable"
Yes, Corinna, I reverted this setting again to the default 384MB heap size
$ peflags --cygwin-heap=0 /usr/sbin/sshd.exe
$ peflags --cygwin-heap=0 /usr/bin/cygrunsrv.exe
Later on, someone has recommended me to downgrade cygrunsrv from 1.36-1 to
1.34-1. This helped, so now under cygwin1.dll 1.7.11 the sshd can be
started. However, the mechanism behaves strange reporting problems:
C:\>net start sshd
The CYGWIN sshd service is starting.
The CYGWIN sshd service could not be started.
The service did not report an error.
More help is available by typing NET HELPMSG 3534.
Having a look into the Event Viewer of my Win2k3 64bit machine, I
... `sshd' service stopped, exit status: 0.
This however is misleading, since I clearly see the sshd running now (I
made sure it was not running before), and indeed I can now connect using
slogin and sftp:

When I try to start sshd from Services menu accessible from the
Administrative Tools menu, I also get a message that the sshd has been
started and then stopped again (even though it actually runs). And in the
Status column no "Started" entry occurs.
Hope this report may help to fix these problems seemingly related to
cygwin1.dll 1.7.11 and cygrunsrv 1.36-1. Now I have downgraded to
cygrunsrv 1.34-1 and sshd can be used, whereas earlier I found that
cygrunsrv 1.36-1 and cygwin1.dll 1.7.9 (I had manually downgraded) also
made sshd launchable as service (but have not documented the messages, I
think similar misleading start-stop messages were given).

Did you revert this setting? It's a hell of a lot of heap, which just
by itself can break fork. sshd doesn't need that much heap anyway.
